When she began to scream, her waist was just passing the level of the elevator floor. She continued to sink, cursing and screaming lustily. The walls stayed just out of reach until they were far above her. The elevator was a diminishing box of light.

Robin's calculations were not begun in the hope the answer would put her back among the living. She could see her death many kilometers below. What she wanted to know was how many seconds. Minutes? Could she possibly have hours to live?

Growing up in the Coven was a help. She knew about centripetal movement, could work that type of problem more readily than she could have dealt with gravitation. Robin had never been in a gravitational field of any consequence.

She began with a known factor, which was the one-fortieth gee that prevailed at the hub. When the elevator floor opened under her, she had begun to fall at a velocity of one-quarter meter per second. But she would not accelerate at that rate. A moving body in a spinning object does not fall along a radial line but appears to move against the direction of spin. In effect, she would be moving in a straight line if viewed from the outside, while the wheel turned under her. Her downward acceleration would at first be slight. Only when she had built up a considerable sidewise velocity would the rate of her fall really begin to increase, and she would experience this as wind coming from the direction opposite the spin.

She looked around quickly. The wind was already strong. She could make out the tops of trees growing from one vertical wall. This was the storied horizontal forest of Gaea. Had Gaea been turning the other way, Robin would have been smashed in seconds or minutes. Since the fall had started at the near wall, she still had time.

There were a few simplified calculations she could make. She was handicapped by not knowing the precise air density in Gaea. She had read it was high, something like two atmospheres at the rim. But at what rate did it fall off as one approached the hub? It never got too thin to breathe, so she could get an estimate by assuming one atmosphere at the hub.

It was oddly comforting to lose herself in the math. She didn't mind having to start over, though she was struck with the futility of the project. She kept at it from a desire to know when death would overtake her. It was important to die right. She gripped the strap of the bag containing Nasu and started again.

She came up with an answer she didn't like, tried again, and a third time when the answers didn't match. Averaging, she got a figure of fifty-nine minutes to impact. As an added bonus there was the impact speed. Three hundred kilometers per hour.

She was falling with her back to the wind. Since she was moving toward both the rim and the approaching wall, it meant her body was at a slight angle. The hub was not quite under her feet. The receding wall was not quite vertical to her. She looked around.

It was breathtaking. Too bad she could not appreciate it.

The Coven, if dropped from her point of departure, would have been a tin can falling down a smokestack. The Rhea Spoke was a hollow tube, flared at the lower end, completely encrusted with trees to dwarf the biggest sequoia. The trees rooted in the walls and grew outward. She could no longer make out even the largest as individual plants; the inner walls were a featureless sea of dark green, all around her. The interior was lit by twin vertical rows of portholes, if one could use that name for openings at least a kilometer in diameter.

She craned her neck, looking into the blast of wind. Nox looked closer. There was something else, something that hovered at the top of her view.

It was the vertical Rhea spokes. They fastened to islands in the Midnight Sea and leaped straight up, converging until they met near the bottom of the spoke and entwined themselves in a monumental pigtail.

She had to see. Twisting in the air, she managed to stabilize herself with her teeth to the gale and opened her eyes. The spokes were in front of her, getting closer by the second.

"Oh Great Mother, hear me now." She mumbled her way through the first death incantation, unable to look away from what had become a rushing dark wall before her. The cable seemed to rotate like a barber pole, the result of her rapid progress past the wound strands.

It took a full minute to sweep past the cables. At the closest approach she held her right arm close to her side. The conviction was strong that if she reached out, she could touch it, though she knew she must be more distant than that. When she was past, she twisted in the air once more and watched the thing recede from her.

One hour didn't sound like that much time. Surely one could remain in absolute terror that long. She began to wonder if something was wrong with her because she no longer felt terror. Before the approach of the cables had rekindled her fright, she had attained a kind of peace. She felt it stealing over her once more and welcomed it. There is a sweet calm that can come with the realization that one's death has arrived, that it will be swift and painless, that there is no good to be gained by sweating and clawing air and cursing fate.

It couldn't last forever. Why couldn't it last just twenty more minutes?

She was skipping back and forth now between fatalism and fear. Knowing there was nothing she could do was not enough. She wanted to live, she was not going to, and there were no words to express the sorrow of that.

Her religion was not one that believed in answered prayers. The Coven did not pray at all, in that sense. They asked nothing. There were things they could demand, positions to be earned in the afterlife, but in a tough spot you were on your own. The Great Mother was not going to interfere in anyone's fate, and it never occurred to Robin to ask Her to. But she did wish there was something she could turn to for help, some power in all this vastness.

And then she wondered if that was what Gaea wanted. Could she listen, all the way down here, minutes from destruction? After the first tremendous shock of it, Robin had not been greatly surprised that Gaea had done this terrible thing. It seemed to mesh well with the insanity she had been talking. But now she wondered why, and the only reason she could think of was to terrorize Robin into acknowledging Gaea as her Lord.

If true, there might be something Gaea could do. Robin opened her mouth, and nothing came out. She tried again and screamed. Through some welcome spiritual alchemy, her fear was transmuted into anger so consuming it shook her more powerfully than the winds.

"Never!" she shouted. "Never, never, never! You stinking cancer! You abomination! You loathsome, repulsive perversion! I'll meet you in your grave, and I will disembowel you and choke you with your reeking guts! I'll stuff you with coals; I'll bite out your tongue; I'll spit you on cold iron and fry you for eternity! I curse you! Hear me now, oh Great Mother, hear me and mark me well! I pledge my shade to the eternal torment of the one called Gaea!"

"Good for you."

"I'm not even started yet! I'll-"

She looked toward her feet. One meter beyond them was a grinning face. There was not much more she could see, considering his angle; just his shoulders, an amazing bulge of chest, and the wings folded on his back.

"You're taking this very calmly."

"Why shouldn't I?" Robin asked. "I thought I had it figured out, and I'm still not sure I was wrong. You swear, by whatever powers you hold holy, that Gaea didn't send you?"

"I swear by the Squadron. Gaea knew she was not tossing you to certain death, but she had no hand in this. I do it freely, on my own."

"I figure I'll hit the wall in about five more minutes."

"Wrong. The bottom of the spoke flares, like a bell, remember? It's enough that you'll come out and fall at a sixty-degree angle over East Hyperion."
